Homo Deus: A Brief History of Tomorrow

Homo Deus is a bold and speculative follow-up to Sapiens, in which Harari shifts from examining humanity's past to predicting its future. He explores how advancements in AI, biotech, and data science might reshape human civilization, potentially leading to the rise of a new species—one that transcends biological limitations. A central argument in the book is that humanity's historical struggles with famine, disease, and war are being replaced by new challenges: immortality, AI, and the pursuit of happiness through technological means. Harari suggests that as humans gain god-like powers through genetic engineering and AI, traditional humanist values—such as free will and individual autonomy—may become obsolete. One of the book's most provocative ideas is the rise of Dataism, a worldview in which data processing becomes the highest value, potentially rendering human decision-making inferior to algorithmic intelligence. Harari warns that as AI surpasses human cognition, power may shift away from individuals to corporations and governments that control vast amounts of data. While Homo Deus is engaging and packed with fascinating insights, it is more speculative than Sapiens and sometimes paints an overly deterministic view of the future. Still, the book raises crucial questions about the ethical and philosophical implications of our technological advancements.
